Title: Improvements in or relating to merocyanine dyes
Inventor: FRY DOUGLAS JAMES
IPC: G03C1/22
Filed: 1956-08-17
Abstract: 3 - Benzoyl - 1 - methyl - 2 - thiohydantoin is prepared by heating equimolecular amounts of benzoyl isothiocyanate and sarcosine on a waterbath.ALSO:Merocyanine dyes of the general formula <FORM:0829790/IV(c)/1> wherein R1 and R2 are alkyl, aralkyl or aryl groups, R3 is a phenyl group, Z is = N or = CH-, n is 0 or 1, m is 0, 1 or 2 and D completes a 5- or 6-membered heterocyclic nucleus, are described.  They may be prepared by reacting a quaternary cyclammonium salt having a reactive thioether or acetanilidovinyl group with a compound of the formula  <FORM:0829790/IV(c)/2> In the examples, D completes a benzthiazole, benzoxazole, thiazoline, pyrroline, quinoline, quinazoline or indolenine nucleus.  In Example 16, 3-benzoyl-1-methyl-2-thiohydantoin is first reacted with b -anilino-acrolein anil hydrochloride in the presence of acetic anhydride and sodium acetate, and the product is reacted with 2-methylbenzthiazole methiodide to give a dye wherein m is 2. According to the Provisional Specification, m may also be 3, and R3 may be an alkyl, aryl, aralkyl or alkoxy group.

Title: Improvements in or relating to electronic circuits employing cold cathode electron tubes
Inventor: KITZ NORBERT
IPC: H03K23/82
Filed: 1963-06-26
Abstract: 1,040,477. Digital electric calculators. BELL PUNCH CO. Ltd. June 23, 1964 [June 26, 1963], No. 25377/63. Heading G4A. An electronic calculating machine of the type described in Specification 1,029,953, has an arrangement by means of which pulses are applied to the cold-cathode tubes in the timing ring counter TR (Fig. 1, not shown), and the storage registers 1R-12R during stand-by periods. This is said to reduce ageing of the tubes. The general principles of operation are similar to those described in Specification 925,308 in which the counter TR has a first stage TO which is conducting during stand-by periods and a second stage T1-T12 having a number of tubes which are operated in sequence one for each cycle of pulses from a pulse generator PG. A third stage T0<1>, also having a cold-cathode tube, is added to form a bistable trigger with T0. The arrangement is that the tubes in TO and T0<1> are fired alternately during stand-by periods, and while the tube T0<1> is conductive bursts of ten pulses are applied to each of the tubes in the stage T1-T12. A delay is provided to ensure that the stage T0<1> is operative for only a small proportion of stand-by time, e.g. 10 to 15%. The gate G11 is opened by a pulse RP produced when T0<1> is operative and the other input- GD to this gate, which is derived from the ouput of the pulse generator PG, is used to chop the RP pulse into ten pulses, thus stepping each register 1R-12R through ten positions. Carry is inhibited as a negative pulse TX is produced also when T0<1> is operative and this is applied to the gate G9 to prevent its opening under the influence of the carry pulse CSO. Means are provided to prevent faulty operation due to the extra pulses and also to ensure that a sequence of ten pulses is completed before calculations are started or resumed. The additional circuitry is fully described with reference to Fig. 2 (not shown).

In a false-twist crimping process, multifilamentary yarn of thermoplastic, synthetic material is heated and then brought into contact with an aqueous liquid for a time less than 60% of the heating time, without interrupting the twist running, so that liquid is deposited on the yarn. The liquid is heated by the yarn and vapourises to penetrate between the filaments so that the yarn is uniformly steam-set. The yarn is untreated for a wet-cooling period and is then twisted by a rotating, frictional, false-twisting device. The heating and wet-cooling times are more than D<0>.<7>/80 and D<0>.<5>/500 seconds (where D is the yarn denier). The yarn material may be polycapramide, polyhexamethylene adipamide, polyethylene terephthalate, polypropylene, or copolymers thereof, the liquid is water, with or without additives such as a surface active agent or colloidal silica, and is applied by a roll rotating partly in the liquid or by jetting. Excess liquid spread by centrifugal force of the rotating yarn and the generated vapour are removed pneumatically by suction. In the apparatus shown, yarn Y from bobbin 1 is advanced by feed roller 2, through a heater 3, between a jetting port 10 (adjustably supplied with water &c. from a tank 8 through a cock 9) and a suction port 11, thence through a false-twister 4, delivery roll 5 to be wound into a package 7.
